Unable to collect WMI data from recent Win10 machines

[AlfieJ]

We're failing to get WMI data from Win10 machines that have recent updates.

Testing has shown that it happens because we're using the asynchronous calls to get the WMI data, and somehow that doesn't work right anymore. We see that using the synchronous calls works fine.

So we need to update COMMON to use the synchronous WMI calls.
